Maize is an important commodity in Indonesia and is vulnerable to maize weevil (Sitophilus zeamais) during storage which can cause a 100% yield loss. Chasew Nut Shell Liquid (CNSL) is a botanical pesticide able to control S. zeamais. Increasing CNSL efficiency and effectiveness requires additional adjuvants, such as solvents and dyes. Natural dyes addition is intended to provide seed markers. This study aimed to determine the best CNSL and natural dye formulation to control maize weevil and maintain maize seeds quality during storage. The research was conducted from August to October 2018 at the Agronomy Laboratory, Faculty of Agroindustry, Yogyakarta Mercu Buana University. The research was a single factor consisted of seven treatments with four replications arranged in a completely randomized design (CRD). Treatments were combinations of CNSL concentrations with the addition of natural dyes from suji leaf and teak leaves with one untreated control. The results of the research showed that CNSL as a seed treatment botanical pesticide could cause mortality and suppress S. zeamais populations and maintain the quality of maize seeds during storage for 12 weeks. Treatments with 20% CNSL formulation concentration and the addition of natural dyes both leaf pleomele or teak leaves could cause higher mortality and push down more populations and also could better maintain seed quality than 10 and 0% CNSL formulation concentrations.

Viral Nervous Necrosis (VNN) disease is one of the major causes of failure in grouper aquaculture activities. The pathogens attack the central nervous system, eyes retina, and reproductive organs. When the rainy season starts, it may generate lower water quality for aquaculture, which becomes a suitable condition for VNN infections in fry cantang grouper. For this reason, there is an emerged need to do the detection of the existence of Viral Nervous Necrosis (VNN) pathogen fry cantang grouper cultured at the rain season. Data analysis was carried out in descriptive ways that aim to make data are presented by the actual situation without giving any treatment so that it can be easily discussed with existing theory to conclude. The examination on the presence of Viral Nervous Necrosis (VNN) disease on fry cantang grouper lived at rain season was conducted using two methods which are conventional PCR and Real-time PCR. From 20 samples of fry cantang grouper taken for this study, 5 samples were detected positive Viral Nervous Necrosis (VNN) its equal to the prevalence of 25%. Histopathological observation on fry cantang grouper infected Viral Nervous Necrosis (VNN) show the appearance of vacuoles on ganglion cell layer, inner nuclear layer, and pigment epitel, a sign of lysis on the liver, vacuoles on the brain, necrosa, and hypertrophy on the brain, and the appearances of melano macrophage center on the kidney. The average water quality in the pond was reported at the temperature of 29.2 0C, salinity 33 ppt, and pH 8.3

The purpose of this study was to determine the effect of giving golden snail meat flour in broiler rations aged 2-5 weeks to the appearance of broiler chickens and to find out what level of golden snail meat flour can give the results of body weight gain, final body weight, feed consumption, and conversion best ration. This study used a Completely Randomized Design with 5 treatments and 3 replications for each treatment. The five treatments were rations without the content of golden snail meat flour as control and rations containing golden snail meat flour 5%, 10%, 15%, and 20%. The parameters observed were bodyweight gain, final body weight, feed consumption, and FCR (Feed Conversion Ratio). The data obtained were analyzed by analysis of variance. If between treatments showed a real difference, then proceed with Duncan's test. The results of the study of the addition of golden snail meat flour (Pomacea canaliculata) in broiler chicken rations had a very significant effect (P<0.01) on the research variables' weight gain, final body weight, and lower FCR. Whereas the consumption of rations had a significant effect (P<0.05). In treatment R2 (10%) gave better results than other treatments (R0, R1, R3, and R4). This means that the treatment of giving golden snail meat flour in the ration apparently can increase the weight gain of broiler chickens. This is because the golden snail contains quite high protein. From the results of this study, it can be concluded that the administration of golden snail meat flour (Pomacea canaliculata) in broiler rations has a very significant effect on increasing weight gain, final weight, and decreasing FCR and significantly influencing ration consumption.

Structure Changing in Maize-Based Agriculture Production in Vietnam: Case Study in Son La Province Dang Thi Thanh Thuy; Nguyen Van Hieu
SEAS (Sustainable Environment Agricultural Science) Vol. 4 No. 1 (2020)
Publisher : Warmadewa University Press

Maize is the primary food resource for livestock, mainly cultivated in the northern mountains, the central provinces, and the central highlands in Vietnam. By studying reliable reports and policies related to maize-based agricultural production in combination with interviews and focus group discussion methods conducted in Son La province, this study specifically analyzes the situation of maize production in Vietnam and impacts of policies for the specific case in Son La province. The research results show that, though the sharp decrease, maize has still been the main crop with an annual cultivation area of over 30% of the country's agricultural land recently. However, maize is only modestly mentioned in some central policies, and no policy at the local level is reserved for maize production. In addition, maize is no longer a crop to attract local farmers’ and authority’ interest, especially since 2015, the transition in maize cultivation area on sloping land to arable land of fruit trees and many other crops has been carried out on a large scale due to some policies by the province, resulting in a sharp decrease in maize cultivated area and production. This might lead to limited results of substantial government policies on maize acreage expansion, maize cultivated area planning, or maize development strategy. Accordingly, some recommendations to improve the situation are provided.

Payment For Environmental Service: An Application in Tourism in Vietnam Nguyen Van Hieu; Dang Thi Thanh Thuy; Nguyen Hoang Nam
SEAS (Sustainable Environment Agricultural Science) Vol. 4 No. 1 (2020)
Publisher : Warmadewa University Press

Payment for Environment/Ecosystem Services (PES) is a market-based approach toward the dual goal of poverty alleviation and forest conservation. In Vietnam, PES has been nationwide applied to the forest environment, namely Payment for Forest Environmental Services (PFES). Nevertheless, the PFES application in forest-based tourism is very limited. To enhance policy implementation in practice, this study analyses a case study in Sapa town, Vietnam. We find that the overlapping revenue of service providers is a substantial issue holding back PFES applications in tourism. Accordingly, we recommend two potential payers for tourism-PFES, including accommodation companies and ticketing companies (based on the revenue from entrance tickets). We then suggest a PFES payment level of 1 percent of total revenue from ticket sales and room charges. Moreover, the study also provides some recommendations to ensure the fairness and transparency in PES application, as well as factual, reflect of the nature of PFES during implementation.
